Frederic and Leopold, the two oldest surviving sons of Albert, avenged their father's death by pursuing the conspirators until they all suffered the penalty of their crimes. With ferocity characteristic of the age, they punished mercilessly the families and adherents of the assassins. Their castles were demolished, their estates confiscated, their domestics and men at arms massacred, and their wives and children driven out into the world to beg or to starve. Sixty-three of the retainers of Lord Balne, one of the conspirators, though entirely innocent of the crime, and solemnly protesting their unconsciousness of any plot, were beheaded in one day. Though but four persons took part in the assassination, and it was not known that any others were implicated in the deed, it is estimated that more than a thousand persons suffered death through the fury of the avengers. Agnes, one of the daughters of Albert, endeavored with her own hands to strangle the infant child of the Lord of Eschenback, when the soldiers, moved by its piteous cries, with difficulty rescued it from her hands.

Elizabeth, the widow of Albert, with her implacable fanatic daughter Agnes, erected a magnificent convent on the spot at Königsburg, where the emperor was assassinated, and there in cloistered gloom they passed the remainder of their lives. It was an age of superstition, and yet there were some who comprehended and appreciated the pure morality of the gospel of Christ.

"Woman," said an aged hermit to Agnes, "God is not served by shedding innocent blood, and by rearing convents from the plunder of families. He is served by compassion only, and by the forgiveness of injuries."

Frederic, Albert's oldest son, now assumed the government of the Austrian provinces. From his uncommon personal attractions he was called Frederic the Handsome. His character was in conformity with his person, for to the most chivalrous bravery he added the most feminine amiability and mildness. He was a candidate for the imperial throne, and would probably have been elected but for the unpopularity of his despotic father. The diet met, and on the 27th of November, 1308, the choice fell unanimously upon Henry, Count of Luxemburg.

This election deprived Frederic of his hopes of uniting Bohemia to Austria, for the new emperor placed his son John upon the Bohemian throne, and was prepared to maintain him there by all the power of the empire. In accomplishing this, there was a short conflict with Henry of Carinthia, but he was speedily driven out of the kingdom.

Frederic, however, found a little solace in his disappointment, by attaching to Austria the dominions he had wrested from the lords he had beheaded as assassins of his father. In the midst of these scenes of ambition, intrigue and violence, the Emperor Henry fell sick and died, in the fifty-second year of his age. This unexpected event opened again to Frederic the prospect of the imperial crown, and all his friends, in the now very numerous branches of the family, spared neither money nor the arts of diplomacy in the endeavor to secure the coveted dignity for him. A year elapsed after the death of Henry before the diet was assembled. During that time all the German States were in intense agitation canvassing the claims of the several candidates. The prize of an imperial crown was one which many grasped at, and every little court was agitated by the question. The day of election, October 9th, 1314, arrived. There were two hostile parties in the field, one in favor of Frederic of Austria, the other in favor of Louis of Bavaria. The two parties met in different cities, the Austrians at Saxenhausen, and the Bavarians at Frankfort. There were, however, but four electors at Saxenhausen, while there were five at Frankfort, the ancient place of election. Each party unanimously chose its candidate. Louis, of Bavaria, receiving five votes, while Frederic received but four, was unquestionably the legitimate emperor. Most of the imperial cities acknowledged him. Frankfort sung his triumph, and he was crowned with all the ancient ceremonials of pomp at Aix-la-Chapelle.

But Frederic and his party were not ready to yield, and all over Germany there was the mustering of armies. For two years the hostile forces were marching and countermarching with the usual vicissitudes of war. The tide of devastation and blood swept now over one State, and now over another, until at length the two armies met, in all their concentrated strength, at Muhldorf, near Munich, for a decisive battle. Louis of Bavaria rode proudly at the head of thirty thousand foot, and fifteen hundred steel-clad horsemen. Frederic of Austria, the handsomest man of his age, towering above all his retinue, was ostentatiously arrayed in the most splendid armor art could furnish, emblazoned with the Austrian eagle, and his helmet was surmounted by a crown of gold.

As he thus led the ranks of twenty-two thousand footmen, and seven thousand horse, all eyes followed him, and all hearts throbbed with confidence of victory. From early dawn, till night darkened the field, the horrid strife raged. In those days gunpowder was unknown, and the ringing of battle-axes on helmet and cuirass, the strokes of sabers and the clash of spears, shouts of onset, and the shrieks of the wounded, as sixty thousand men fought hand to hand on one small field, rose like the clamor from battling demons in the infernal world. Hour after hour of carnage passed, and still no one could tell on whose banners victory would alight. The gloom of night was darkening over the exhausted combatants, when the winding of the bugle was heard in the rear of the Austrians, and a band of four hundred Bavarian horsemen came plunging down an eminence into the disordered ranks of Frederic. The hour of dismay, which decides a battle, had come. A scene of awful carnage ensued as the routed Austrians, fleeing in every direction, were pursued and massacred. Frederic himself was struck from his horse, and as he fell, stunned by the blow, he was captured, disarmed and carried to the presence of his rival Louis.

The spirit of Frederic was crushed by the awful, the irretrievable defeat, and he appeared before his conqueror speechless in the extremity of his woe. Louis had the pride of magnanimity and endeavored to console his captive.

"The battle is not lost by your fault," said he. "The Bavarians have experienced to their cost that you are a valiant prince; but Providence has decided the battle. Though I am happy to see you as my guest, I sympathize with you in your sorrow, and will do what I can to alleviate it."

For three years the unhappy Frederic remained a prisoner of Louis of Bavaria, held in close confinement in the castle at Trausnitz. At the end of that time the emperor, alarmed at the efforts which the friends of Frederic were making to combine several Powers to take up arms for his relief, visited his prisoner, and in a personal interview proposed terms of reconciliation. The terms, under the circumstances, were considered generous, but a proud spirit needed the discipline of three years' imprisonment before it could yield to such demands.

It was the 13th of March, 1325, when this singular interview between Louis the emperor, and Frederic his captive, took place at Trausnitz. Frederic promised upon oath that in exchange for his freedom he would renounce all claim to the imperial throne; restore all the districts and castles he had wrested from the empire; give up all the documents relative to his election as emperor; join with all his family influence to support Louis against any and every adversary, and give his daughter in marriage to Stephen the son of Louis. He also promised that in case he should fail in the fulfillment of any one of these stipulations, he would return to his captivity.

Frederic fully intended a faithful compliance with these requisitions. But no sooner was he liberated than his fiery brother Leopold, who presided over the Swiss estates, and who was a man of great capacity and military energy, refused peremptorily to fulfill the articles which related to him, and made vigorous preparations to urge the war which he had already, with many allies, commenced against the Emperor Louis. The pope also, who had become inimical to Louis, declared that Frederic was absolved from the agreement at Trausnitz, as it was extorted by force, and, with all the authority of the head of the Church, exhorted Frederic to reassert his claim to the imperial crown.

Amidst such scenes of fraud and violence, it is refreshing to record an act of real honor. Frederic, notwithstanding the entreaties of the pope and the remonstrances of his friends, declared that, be the consequences what they might, he never would violate his pledge; and finding that he could not fulfill the articles of the agreement, he returned to Bavaria and surrendered himself a prisoner to the emperor. It is seldom that history has the privilege of recording so noble an act. Louis of Bavaria fortunately had a soul capable of appreciating the magnanimity of his captive. He received him with courtesy and with almost fraternal kindness. In the words of a contemporary historian, "They ate at the same table and slept in the same bed;" and, most extraordinary of all, when Louis was subsequently called to a distant part of his dominions to quell an insurrection, he intrusted the government of Bavaria, during his absence, to Frederic.

Frederic's impetuous and ungovernable brother Leopold, was unwearied in his endeavors to combine armies against the emperor, and war raged without cessation. At length Louis, harassed by these endless insurrections and coalitions against him, and admiring the magnanimity of Frederic, entered into a new alliance, offering terms exceedingly honorable on his part. He agreed that he and Frederic should rule conjointly as emperors of Germany, in perfect equality of power and dignity, alternately taking the precedence.

With this arrangement Leopold was satisfied, but unfortunately, just at that time, his impetuous spirit, exhausted by disappointment and chagrin, yielded to death. He died at Strasbourg on the 28th of February, 1326. The pope and several of the electors refused to accede to this arrangement, and thus the hopes of the unhappy Frederic were again blighted, for Louis, who had consented to this accommodation for the sake of peace, was not willing to enforce it through the tumult of war. Frederic was, however, liberated from captivity, and he returned to Austria a dejected, broken-hearted man. He pined away for a few months in languor, being rarely known to smile, and died at the castle of Gullenstein on the 13th of January, 1330. His widow, Isabella, the daughter of the King of Arragon, became blind from excessive grief, and soon followed her husband to the tomb.

As Frederic left no son, the Austrian dominions fell to his two brothers, Albert III. and Otho. Albert, by marriage, added the valuable county of Ferret in Alsace to the dominions of the house of Austria. The two brothers reigned with such wonderful harmony, that no indications can be seen of separate administrations. They renounced all claim to the imperial throne, notwithstanding the efforts of the pope to the contrary, and thus secured friendship with the Emperor Louis. There were now three prominent families dominant in Germany. Around these great families, who had gradually, by marriage and military encroachments, attained their supremacy, the others of all degrees rallied as vassals, seeking protection and contributing strength. The house of Bavaria, reigning over that powerful kingdom and in possession of the imperial throne, ranked first. Then came the house of Luxembourg, possessing the wide-spread and opulent realms of Bohemia. The house of Austria had now vast possessions, but these were widely scattered; some provinces on the banks of the Danube and others in Switzerland, spreading through the defiles of the Alps.

John of Bohemia was an overbearing man, and feeling quite impregnable in his northern realms beyond the mountains, assumed such a dictatorial air as to rouse the ire of the princes of Austria and Bavaria. These two houses consequently entered into an intimate alliance for mutual security. The Duke of Carinthia, who was uncle to Albert and Otho, died, leaving only a daughter, Margaret. This dukedom, about the size of the State of Massachusetts, a wild and mountainous region, was deemed very important as the key to Italy. John of Bohemia, anxious to obtain it, had engaged the hand of Margaret for his son, then but eight years of age. It was a question in dispute whether the dukedom could descend to a female, and Albert and Otho claimed it as the heirs of their uncle. Louis, the emperor, supported the claims of Austria, and thus Carinthia became attached to this growing power.

John, enraged, formed a confederacy with the kings of Hungary and Poland, and some minor princes, and invaded Austria. For some time they swept all opposition before them. But the Austrian troops and those of the empire checked them at Landau. Here they entered into an agreement without a battle, by which Austria was permitted to retain Carinthia, she making important concessions to Bohemia. In February, 1339, Otho died, and Albert was invested with the sole administration of affairs. The old King of Bohemia possessed vehemence of character which neither age nor the total blindness with which he had become afflicted could repress. He traversed the empire, and even went to France, organizing a powerful confederacy against the emperor. The pope, Clement VI., who had always been inimical to Louis of Bavaria, influenced by John of Bohemia, deposed and excommunicated Louis, and ordered a new meeting of the diet of electors, which chose Charles, eldest son of the Bohemian monarch, and heir to that crown, emperor.

The deposed Louis fought bravely for the crown thus torn from his brow. Albert of Austria aided him with all his energies. Their united armies, threading the defiles of the Bohemian mountains, penetrated the very heart of the kingdom, when, in the midst of success, the deposed Emperor Louis fell dead from a stroke of apoplexy, in the year 1347. This event left Charles of Bohemia in undisputed possession of the imperial crown. Albert immediately recognized his claim, effected reconciliation, and becoming the friend and the ally of the emperor, pressed on cautiously but securely, year after year, in his policy of annexation. But storms of war incessantly howled around his domains until he died, a crippled paralytic, on the 16th of August, 1358.
